Hi All
I have an Australian delivered 2019 plus4 without DRL’S. Has any one followed the wiring harness and determined if the wiring is in place for DRL’S ( as there is quite a few unused plugs on the standard harness ) or do I have to start from scratch.
Hope you can help.

According to the wiring schematic there are no dedicated DRL cables in the loom. There is cabling for the optional front foglights (blue/yellow) and wing top sidelights (red/orange and red/black) though which would explain the cable tails you have found.

To fit DRL's you would need to provide a fused ignition switch feed and have that provide power to same via a diode relay controlled by headlights such that DRL's extinguish or dim when latter are on. It depends on the legislation for such in your country.

In the UK at least the later cars are wired so the parking / sidelights front and rear come on with the ignition.
On my previous 2006 Roadster I had the dealer change the wiring to do that.

As John V6 has said all UK cars have the sidelights come on with the ignition that is all that is required on models that were in production before 2011 as that counts as DLR. Why not just fit some LED bulbs in the the sidelights.


European Union Directive 2008/89/EC required all passenger cars and small delivery vans first type[clarification needed] approved on or after 7 February 2011 in the EU to come equipped with daytime running lights.[14][15][16] European Union Directive 2008/89/EC ended validity on 31 October 2014, implicitly repealed by the replacement Regulation (EC) No 661/2009.[17][18] The mandate was extended to trucks and buses in August 2012.[19] Functional piggybacking,[colloquialism] such as operating the headlamps or front turn signals or fog lamps as DRLs, is not permitted;[20] the EU Directive requires functionally specific daytime running lamps compliant with ECE Regulation 87 and mounted to the vehicle in accordance with ECE Regulation 48.[21] DRLs compliant with R87 emit white light on an axis of between 400 and 1,200 candela with an apparent surface of 25 cm2 to 200 cm2 with an additional requirement of between 1 and 1,200 candela in a defined field.[22]

Only on the 3.7 Roadster's I believe John, in the UK at least, possibly CX series as well.

Richard, certainly Hawkis Plus 4 doesn't have the lights on automatically and it is newer than Belle.

Not sure about the CX. You would hope by now they have DLRs

Thank you all for your comments.Looks like I do a full from scratch wiring job or just use one of the existing ignition switched connectors near the horn and not worry about headlight dimming as we only have to do a roadworthy at change of owners here.
Thanks again

Welcome to TM Colin.

I tapped off the permanent wiper live feed. There appears to be enough capacity to run a couple of super bright 800 Lumen led jobbies as I haven’t popped a fuse so far after 18 months.



Have fun and enjoy your car

Rog, looks very smart. I notice you are using the indicator lights, where do you keep your indicators?

I see from Keith’s post above that it’s called “functional piggybacking”.... The indicators and DRL’s share the same lamp. The bulbs used have some clever integrated electronics to enable the DLR's to remain always on until the indicators are activated and then the bulb changes to flashing orange. When the indicator is cancelled the DRL slowly phases back to white. They are also deactivated when the main lights are switched on as they are too bright for night use.
